The other day my laptop shutdown after about 2 hours. I was in the middle of updating to ubuntu meerkat beta alpha 11. the power cord came out and the battery died. I have been using Puppy Linux but i cannot fix my system. Does anyone know how to fix it without losing my files and things from ubuntu 10.04 without having to perform a full install from scratch? Please help.

While this info is appreciated, I’d also like info about how to install 10.10 from scratch on a system that contains 10.04.
This info is nowhere on the net yetthis situation exists for many people who have saved their home partition and want an entirely new build

I have three partitions for the ubuntu install, /home, /root, /swap. when ever i would install a new version or if i was skipping versions, i would boot into the desktop disc, and use partition editor to format the /root , and set the /home partition the same as it was before and use the same username and passwords and i never had a problem with my settings or files.
